Singer Ashlee Simpson and Evan Ross want to keep their marriage "fun and exciting".
"Ashlee and Evan made a promise to each other that they want to keep their marriage fun and exciting," a source told OK! magazine, reports femalefirst.co.uk.
The pair will soon become proud parents.
The singer's sister Jessica Simpson had held a "chill" baby shower for Ashlee at her home.
"It was beautiful weather and her house was the perfect setting ... so gorgeous. It was very chill and almost like just a get-together than a traditional shower. It wasn't focussed on games (and was) more like a big party," a guest shared.
